When you compare Biden to Trump vs. the effects on the Palestinians, were Trump president again, he would not just help the Israelis exterminate the Palestinians, but encourage them to do so quickly- as he’s already told Bibi to “finish it”. So your dichotomy is more than a bit disingenuous .

Your right that it ain’t your fault when other people vote for someone else, but the Bernie crusaders have NEVER owned up to that being 99% of what happened both times around, other people voted for someone else, and that number of other people was well surmountable by turning out at voting age share at a minimum, let alone how much more young voters could take in over representation if they could be fucking bothered to do anything but get mad at other people for not voting the way the non voters wanted them to.
